Research and manufacture water-based fire retardant coating mixture using graphene additive for natural wood

Abstract

Intumescent fire-retardant coatings, especially water-based intumescent fire-retardant coatings, are increasingly attracting attention due to their environmentally friendly properties. In this work, we have successfully manufactured a water-based fire retardant coating mixture using graphene additive for natural wood with three main ingredients (ammonium polyphosphate acidifying agent, pentaerythritol carbonizing agent, melamine blowing agent), and some additives including graphene. We investigated the influence of graphene content on the fire retardant effectiveness of the mixture when coated on natural wood (pine wood) according to UL94-V standard. Test results show that the content of graphene contributes to enhancing the fire retardant effectiveness of the manufactured mixture. SEM imaging method was used to analyze and explain the test results. Some specifications of the manufactured mixture are also analyzed and evaluated. The findings of this research provide a solution to enhance fire resistance for natural wood structures using environmentally friendly materials.
